9、r Loop Tack Test3.Terminology3.1 Definitions:3.1.1 Many of the terms found in these test methods aredefined in Terminology D907.4.Summary of Test Method4.1 These test methods involve allowing a loop of pressure-sensitive adhesive with its backing to be brought into con-trolled contact with a 1 in.2(
10、25 by 25 mm)surface of stainlesssteel,with the only force applied being the weight of thepressure-sensitive article itself.The pressure-sensitive article isthen removed from the substrate,with the force to remove thepressure-sensitive article from the adherend measured by arecording instrument.4.2 T
